Oven Puffed Pancake

I asked for a cast iron skillet for Christmas this past year, and Santa delivered! I know a few people that rave about cast iron cookware, and I decided to make an oven puffed pancake in it. I used a recipe similar to this one from Cooking Light. I was quite impressed with how it puffed up, and it wasn't too heavy. I definitely want to make this again.
